Hadith 3449

أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الصَّمَدِ بْنِ عَلِيٍّ الْمَوْصِلِيُّ ، قَالَ : حَدَّثَنَا مَخْلَدٌ ، عَنْ سُفْيَانَ ، عَنْ سَالِمٍ ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ ، عَنْ ابْنِ عَبَّاسٍ ، قَالَ : " أَتَاهُ رَجُلٌ ، فَقَالَ : إِنِّي جَعَلْتُ امْرَأَتِي عَلَيَّ حَرَامًا ، قَالَ : كَذَبْتَ لَيْسَتْ عَلَيْكَ بِحَرَامٍ ، ثُمَّ تَلَا هَذِهِ الْآيَةَ : يَأَيُّهَا النَّبِيُّ لِمَ تُحَرِّمُ مَا أَحَلَّ اللَّهُ لَكَ سورة التحريم آية 1 ، عَلَيْكَ أَغْلَظُ الْكَفَّارَةِ ، عِتْقُ رَقَبَةٍ " .
´It was narrated that Ibn 'Abbas said:` "A man came to him and said: 'I have made my wife forbidden to myself.' He said: 'You are lying, she is not forbidden to you.' Then he recited this Verse: 'O Prophet! Why do you forbid (for yourself) that which Allah has allowed to you.' (And he said): 'You have to offer the severest form of expiation: Freeing a slave.'"

Explanation & Benefits
Hafiz Muhammad Ameen
(1) "You have lied," meaning your declaring your wife forbidden (haram) for yourself is a lie and an incorrect statement, because how can a wife become forbidden? Yes, if it is said with the intention of divorce, that is a different matter.

(2) "The strictest expiation (kaffarah) will be upon you," because you have uttered an extremely vile statement. The wife will not become forbidden, but you will have to bear the punishment for this vile utterance. (See: Hadith 3411)

(3) "To free a slave"—in addition to the Noble Qur'an, feeding or clothing the poor, or fasting, are also mentioned. It is possible that this person was affluent, so Ibn Abbas (radi Allahu anhu) considered it necessary to impose strictness upon him and instructed him to free a slave. And Allah knows best.
